Hot Melt Pressure Sensitive Adhesive

Hot Melt Pressure Sensitive Adhesives (HMPSA) are 100% solid adhesives, which adhere to a variety of substrates at room temperature by merely application of light hand pressure. They are soft, permanently tacky adhesives, which exhibit a balance of green strength and cohesive strength. Just like hot melt adhesives they become low viscosity fluids at elevated temperatures when they can be applied .the difference however is that, HMPSA remains sticky after cooling, whereas a normal Hma becomes non sticky on cooling.
